2 Claims.

The invention relates to a window sash fitting, and more especially to aremovable sash assembly for old and new windows.

The primary object of the invention is the provision of an assembly ofthis character, wherein its elements are prefabricated, and in thisconnection such elements can be readily and easily mounted in a windowframe, either old or new, so that the sash will be balanced for slidingadjustment without the use of weights, chains, cords, or the like, andalso that such sash may be conveniently removed from the window frame,without requiring the use of tools or the detachment of any part of thesaid window frame.

Another object of the invention is the provision of an assembly of thischaracter, wherein it is novel and unique for the holding of the sashesof a window in place in its frame, yet permitting their removaltherefrom with ease and dispatch,

the sashes being readily slidable when installed so that the same may beadjusted in the opening and closing of the window.

A further object of the invention is the provision of an assembly ofthis character, wherein each sash carries two sash balancers, thesebeing essential for the removable fitting of the sash to the windowframe and provide an equal tension at all times on the window jambitself whether the sash is in open or closed position, while equallyessential to the removable character of the sash :`l

is the fact that the slide rail from which the sash is disengaged is setat a slight angle of about l5 degrees to allow for positive clearance ofthe sash from the window frame.

A still further object of the invention is the provision of an assemblyof this character, wherein the same is a knock-down type, and involves aminimum number of parts, so that such assem bly can be set up with easeand dispatch.

A still further object of the invention is the provision of an assemblyof this character, which is simple in construction, thoroughly reliableand efficient in the working thereof, strong, durable, neat andattractive in appearance when set up, assures quick and easy removal ofthe sash from a window frame as well as replacement, and inexpensive tomanufacture and install.

With these and other objects in View the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in the accompanyingdrawing, which discloses the preferred embodiment of the invention, andpointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is an elevation, partly broken away at intervals of a windowframe with the removable sash assembly in accordance with the invention.

Figure 2 is an enlarged sectional view taken on the line 2-2 of Figure llooking in the direction ef the arrows.

Figure 3 is an exploded fragmentary plan view of a modified form of sashassembly in accordance with the invention.

Similar reference characters indicate corresponding parts through theseveral Views in the drawing.

Referring to the drawing in detail, A designates generally awindow-frame, wherein slides the upper and lower sashes B and C,respectively, the latter being of the usual well known construction withthe slight exceptions as will be hereinafter more fully described.

The said window-frame A is provided on its inner side faces with theusual parting stop I0, the blind stop II, and the front stop I2,respectively, between which the sashes B and C operate. The meetingrails of each of the sashes B and C are channeled as at I3 and I4,respectively, in matched relation and correspondingly to the partingstrips or stops I0, the channels I3 being of greater depth than thechannels I4, so that such sashes B and C can be shifted crosswise of thewindow-frame A to enable the removal of such sashes or the replacementof the same after removal from the window-frame,

At the right-hand inner face of the windowframe A between the stops I0,Il, and I2, are the prefabricated inserts in the form of strips I5, eachhaving its exposed surface set at an angle of approximately 5 degrees,as at I6, to allow for positive clearance of the sash cooperatingtherewith from the Window-frame A as will be clearly apparent from thedrawing. Intermediate of this surface I6 is a semi-circular bead Ilwhich is coextensive with the longitudinal extent of the strip l5, thebead being approximately one-eighth of an inch in depth. The spacesbetween the stops I0, II and I0, I2, as well as the spaces on eitherside of the stop 23 form guide rails or spaces in which the sashesslide.

The vertical side members I8 of each of the sashes B and C at theirouter faces meeting the rails or strips I5, each is angled as at I9correspondingly to the surface I6, and such angled surface I9 hasintermediate thereof a longitudinally directed semicircular groove 2Qreceiving the bead Il. The side members I8 are constructed in the mannerjust mentioned only at the righthand side of the window-frame A, whilethe vertical side members 2| of the sashes B and C at the left-hand sideare of the usual construction or formation, excepting the channels I3 asheretofore mentioned.

Installed in each vertical side member 2l at the left-hand side of eachsash B and C is a pair of spaced upper and lower sash balancers 22 whichfrictionally contact the left-hand side of the window-frame A when thesaid sashes are tted thereto, and maintain these sashes to normally havethe beads il interfitting the grooves 20 for sliding engagement of suchsashes in the frame A and to hold the said sashes B and C in adjustedpositions Without the use of weights, cords or the like as is customaryfor hanging in the windowframe A. The said balancers 22 keep both sashesB and C snug against the sliding rails and in this manner eliminates theneed for weather stripping on one side of the window.

Now, when it is desired to remove either or both sashes B and C from thewindow-frame A it is only necessary to push such sashes to the lefthandside of the latter to have the bead I1 at the right-hand side of thesaid window-frame clear the channel or groove 20 and on outward swingingmovement the sash will become removed from such window frame.

In Figure 3 of the drawing there is shown a slight modification of theassembly constructed Yin accordance with the invention, wherein theright-hand jamb side of the window-frame has the parting stop 23, theangled surfaces 24 and beads 25, respectively, involved in a single unit26, and in both the preferred and modiiied forms of construction, eachcan be manufactured as a kit, prefabricated and disposed of foradaptation to old or new windows, the sashes being machined forcooperative tting to the kit.

What is claimed is 1. The combination of a window frame and a pair ofsliding sashes therein, pairs of permanently fixed blind stops and frontstops afxed to the window frame on the front and rear faces thereof,respectively and extending the entire length of the frame, and a pair ofpermanently amxed parting stops on the opposite sides of the frame, saidpairs of blind stops, front stops and parting stops forming two pairs ofsliding rails facing each other in juxtaposed position, said pair ofsashes having facing channels for loosely engaging the ends of saidparting stops whereby either of said sashes may be moved parallel to aline extending between said parting stops, the sliding rails at one sideof said frame each having a bead and a portion of the sashes engaged insaid last named rails, each having a groove engaged by its correspondingbead, said last named sliding rails each having its exposed surface setat an inclination to a vertical plane which is at right angles to theplane of its sash, and to form an angle with the plane of the other pairof sliding rails, whereby to allow for clearance of the sash during itsremoval from the window frame, the opposite portions of the sashes fromthose having grooves having plane surfaces engaging plane surfaces ontheir corresponding rails, and at least two spring pressed membershoused in each sash for engaging the plane surfaces of the said rails,the said sashes being of greater Width than the distance between theinnermost portions of the opposed sliding rails and less than thedistance between the outermost portion of those rails accommodating theplungers and the innermost portions of the opposite rails whereby toleave spaces between the sides of the sashes having said spring pressedmembers and the rails engaged thereby to permit removal of the railsWithout disturbing said blind stops, front stops and parting stops.

Z. The combination of a window frame and a pair of sliding sashestherein, pairs of permanently fixed blind stops and front stops affixedto the window frame on the front and rear faces thereof, respectivelyand extending the entire length of the frame and a pair of permanentlyaixed parting stops on the opposite sides of the frame, said pairs ofblind stops, front stops and parting stops forming two pairs of slidingrails facing each other in juxtaposed position said pair of sasheshaving facing channels for loosely engaging the ends of said partingstops whereby either of said sashes may be moved parallel to a lineextending between said parting stops, the sliding rails at one side ofsaid frame each having a bead and a portion of the sashes engaged insaid last named rails, each having a groove engaged by its correspondingbead. said last named sliding rails each having its exposed surface setat an inclination to a vertical plane which is at right angles to theplane of its sash. and to form an angle with the plane of the other pairof sliding rails, whereby to allow for clearance of the sash during itsremoval from the window frame, the opposite portions of the sashes fromthose having grooves having plane surfaces engaging plane surfaces ontheir corresponding rails, and at least two spring pressed membershoused in each sash for engaging the plane surfaces of the said rails,the said sashes being of greater width than the distance between theinnermost portions of the opposed sliding rails and less than thedistance between the outermost portion oi those rails accommodating theplungers and the innermost portions of the opposite rails whereby toleave spaces between the sides of the sashes having said spring pressedmembers and the rails engaged thereby to permit removal of the railswithout disturbing said blind stops, front stops and parting stops, saidspring pressed members including a pair of spring pressed plungershaving ilat faces for engaging the plane surface of said rails.
